5.2 PRODUCT SETUP
The
DNP DEFAULT DEADBAND
settings group the L60 analog input data into the following types: current, voltage, power, energy, power factor, and other.
Each setting represents the default deadband value for all analog input points of that type. For example, to trigger unsolic-
ited responses from the L60 when any current values change by 15 A, the
be set to "15". Note that these settings are the deadband default values. DNP object 34 points can be used to change dead-
band values, from the default, for each individual DNP analog input point. Whenever power is removed and re-applied to
the L60, the default deadbands will be in effect.
The L60 relay does not support energy metering. As such, the
DEFAULT DEADBAND
NOTE
The
DNP TIME SYNC IIN PERIOD
Changing this time allows the DNP master to send time synchronization commands more or less often, as required.
The
DNP MESSAGE FRAGMENT SIZE
fragment sizes allow for more efficient throughput; smaller fragment sizes cause more application layer confirmations to be
necessary which can provide for more robust data transfer over noisy communication channels.
When the DNP data points (analog inputs and/or binary inputs) are configured for Ethernet-enabled relays, check
the "DNP Points Lists" L60 web page to view the points lists. This page can be viewed with a web browser by enter-
ing the L60 IP address to access the L60 "Main Menu", then by selecting the "Device Information Menu" > "DNP
NOTE
Points Lists" menu item.
The
DNP OBJECT 1 DEFAULT VARIATION
default variation number for object types 1, 2, 20, 21, 22, 23, 30, and 32. The default variation refers to the variation
response when variation 0 is requested and/or in class 0, 1, 2, or 3 scans. Refer to the DNP implementation section in
appendix E for additional details.

The DNP binary outputs typically map one-to-one to IED data points. That is, each DNP binary output controls a single
physical or virtual control point in an IED. In the L60 relay, DNP binary outputs are mapped to virtual inputs. However, some
legacy DNP implementations use a mapping of one DNP binary output to two physical or virtual control points to support
the concept of trip/close (for circuit breakers) or raise/lower (for tap changers) using a single control point. That is, the DNP
master can operate a single point for both trip and close, or raise and lower, operations. The L60 can be configured to sup-
port paired control points, with each paired control point operating two virtual inputs. The
setting allows configuration of from 0 to 32 binary output paired controls. Points not configured as paired operate on
POINTS
a one-to-one basis.
The
DNP TCP CONNECTION TIMEOUT
there is no data traffic on a DNP TCP connection for greater than the time specified by this setting, the connection will be
aborted by the L60. This frees up the connection to be re-used by a client.
Relay power must be re-cycled after changing the
effect.

The binary and analog inputs points for the DNP protocol, or the MSP and MME points for IEC 60870-5-104 protocol, can
configured to a maximum of 256 points. The value for each point is user-programmable and can be configured by assigning
FlexLogic operands for binary inputs / MSP points or FlexAnalog parameters for analog inputs / MME points.
